Introducing Post Bridge Actions

One deposit. Automatic execution. Immediate operational readiness.

Crosschain onboarding has come far, but one bottleneck remains: after bridging funds, users still need to switch networks, locate the correct contract, and manually complete their final onchain action. That friction costs conversions.

Post Bridge Actions (PBA) eliminate that final step. Your users send funds once. Rhino.fi bridges them to the destination chain and automatically executes the target action. They land in the correct operational state without any manual intervention.

How It Works

Smart Deposit Addresses already removed the first layer of friction by giving users one deposit surface that accepts funds from any supported chain. Post Bridge Actions extend this capability by handling what comes after the bridge.

A user deposits funds to their Universal Smart Deposit Address. Rhino.fi routes those funds to the destination chain and immediately executes the specified onchain action on their behalf. This could be a vault deposit, a mint operation, a stake, or any other protocol interaction your system requires.

The user experience collapses from multiple steps across different interfaces into a single deposit.

What You Can Automate

Post Bridge Actions support the full range of terminal operations in your funding flow:

• Deposits into vaults, margin accounts or trading structures

• Minting wrapped assets, yield-bearing tokens or protocol-specific instruments

• Automated conversion into yield products or structured positions

• Supply, repay, stake or liquidity provision operations

• Direct CEX-to-protocol flows that bypass manual wallet interactions

Rhino.fi handles routing, execution and state management. You define the target action and Post Bridge Actions deliver users to that end state.

The Alternative

Most teams build this layer themselves. They generate custodial or self-custodial deposit addresses, monitor inbound transfers, and maintain the mapping logic between deposits and target actions. Some use enterprise custody solutions like Fireblocks as middleware.

The operational cost is significant: infrastructure maintenance, monitoring systems, transaction management, error handling and ongoing development as your product evolves. For B2B teams, this complexity rarely justifies the benefit of a fully non-custodial flow.

Post Bridge Actions remove that burden. Rhino.fi provides the deposit surface, handles the routing and executes the post-bridge action. Your integration effort focuses on defining the target state, not managing infrastructure.

Live in Production

Extended, a perpetual DEX on Starknet, was the first integration. Their platform requires funds to sit in user-specific trading vaults before positions can be opened. The legacy flow forced users to bridge manually, switch to Starknet, locate their vault contract and complete a deposit before they could trade.

With Post Bridge Actions, a user deposits once from any chain. Rhino.fi bridges to Starknet and deposits directly into their trading vault. They arrive ready to open positions immediately. In one click. 

The result is simple: faster activation and higher conversion across the onboarding flow.

Who Benefits

Post Bridge Actions are built for teams whose products require a final onchain interaction before users can operate. This includes:

• Perpetual and derivatives DEXes with vault-based margin systems

• Payment companies wanting single-click multi-chain settlement and instant crediting

• Remittance prpviderd wanting single-click multi-chain cross-boarder transfers

• Yield platforms, structured products and automated vaults

• Neobanks and card issuers auto-depositing bridged assets into user accounts

• Appchains with native staking or vault structures

• Web3 wallets crediting balances on bridge arrival

• RWA platforms with minting or deposit prerequisites

• Any protocol where manual post-bridge steps create drop-off

If your onboarding flow ends with "now switch networks and complete the deposit manually," Post Bridge Actions replace that instruction with automatic execution.

Getting Started

Post Bridge Actions are available now for production integration. If you want to remove the final manual step from your onboarding flow, we'll work with you to configure the target actions and test the integration before going live.

Next steps:

• Review the technical documentation to understand integration requirements

• Contact the Rhino.fi team to discuss your use case and initiate implementation

• Schedule a technical walkthrough to see Post Bridge Actions in your specific context
